Bubonic plague effected on European feudalism as it hastened feudalism's decline due to the system's reliance on peasant labor.
Answer: Option A
<u>Explanation:
</u>
Bubonic Plague was an epidemic disease which had spread in Europe in 14th century and resulted in the death of 30-60% of European population. This deadly disease has also resulted in the decline of Feudalism.
The system of feudalism largely dependent of the peasants or labourers which were known as serfs who were employed by the knights and worked under the barons( who worked for the kings).
The Black death or the plague had affected the peasants the most hence breaking the system as the now there was great shortage of labour.
Answer:
No.
Explanation:
No, writing "are a" in a sentence is not correct because ''are '' is used for plural objects or things such these are boys, footballs are big etc while n the other hand, ''a'' is used for singular objects such as a ball, a boy etc so these two words which are used in separate sentences not in a single sentence with each other. so we can say that we can't write "are a" in a single sentence.
Although Jaguars are the biggest cats in North and South America, they are not invincible. Biologists have guessed that at least 64 jaguars have been killed in Arizona since the 1900’s. One of the reasons that jaguars are being killed is for everywhere is for their beautiful coat and teeth, which in some cultures is belived to protect the wearer from snakebites that is why
Answer:
1. Focus
2. Aphelion
3. Ellipse
4. Semimajor axis
5. Perihelion
6. Eccentricity
Explanation:
In Kepler's first law of planetary motion, he says that planets orbit around the sun, not in perfect circles, but in ellipses (3.) the Earth also orbits the sun in this shape. The shape of the ellipse is determined by two focii. The closer these two points are to each other, the more the ellipse will resemble a circle.
The moon for example, orbits around the Earth. The moon is not always at the same distance from the Earth in all points of the orbit. So the shape is an ellipse, which is made with Earth as one of its focus(1.).
Eccentricity(6.) describes the flatness the orbit is, or how elliptical the orbit is. Remember Kepler's first law, he says that planets move in elliptical orbits and not perfect circles. So it is simply how different from a perfect circle an orbit is. Pluto is known to have a large eccentricity.
Because of the shape of an ellipse, there are going to be points where a planet is closest to the sun and where a planet is farthest from the sun. This is where Kepler's 2nd law of planetary motion comes in. When the planet is closest to the sun, this is called the perihelion (5.) where a planet would be traveling the fastest at this point of the orbit. When the planet is at its farthest point from the sun, this is called the aphelion (2.) where a planet would be traveling the slowest.
The third law of Kepler describes the relationship between the period and the average distance of the sun. The semimajor axis(4.) is the average distance of the planet object from the sun and is measured in Astonomical units (AU). The period is measured in years.
